Derivative of `sinpi(2x)` evaluates pi numerically when differentiating

5

With Symbolics v4.2.3 we get ```julia julia> @variables x 1-element Vector{Num}: x julia> sinpi(2x) sinpi(2x) julia> Symbolics.derivative(sinpi(2x), x) 6.283185307179586cospi(2x) ``` Whereas we would expect the result `2πcospi(2x)`. Somehow the `π`...

One of the cases for handling matrices containing NaN is broken https://github.com/JuliaLinearAlgebra/GenericSVD.jl/blob/07156afd31346a7245cd08585d67d853d6a952c8/src/GenericSVD.jl#L157-L163 The `return B.dv+NaN` should be changed to `return B.dv .+ NaN`.

Make Pluto boilerplate formatted according to JuliaFormatter

This is a very minor thing which has annoyed me for some time. It would be nice if the boilerplate added by Pluto was formatted in such a way that...

Incorrectly parsed tuple assignment in let statement

1

The statement ```julia let (x, y) = (0, 1) y end ``` is valid Julia code. However, tree-sitter doesn't like it. Using the Emacs `julia-ts-mode` with `treesit-explore-mode` I get the...

There doesn't exist any `mag_get_str`, I think this would be convenient to have. There is currently only `mag_print` for printing and the output format for that is not the most...

There is a (currently open) [PR](https://github.com/JuliaLang/julia/pull/51362) for Julia about using `ScopedValues` for `setprecision` with `BigFloat`. If this ends up being merged it seems like a good idea for us to...

Flag for enabling warnings when converting from `AbstractFloat`

13

I find that one of the easiest mistakes to make when working with `Arblib` in Julia is to accidentally use `Float64` for some internal computations. For example for `x::Arb` it's...

Plotting and subtyping `AbstractFloat`

7

I want to be able to plot the `Number` types we define in Arblib.jl directly using Plots.jl. Currently `plot([Arb(1)])` fails because `float(::Arb)` defaults to `AbstractFloat(::Arb)` which is not defined. There...

The function `acb_hypgeom_si` which computes the sine integral `Si` in Arb is named `hypgeom!` in Arblib since it assumes the `si` means signed integer. Adding this as an issue here...

Handling of Inf and Nan for `nfloat`

2

**Describe the bug** Multiplication of `nfloat` values does not seem to allow for infinite values even if the flag is set to `NFLOAT_ALLOW_INF`. **Steps to reproduce** Running the following code...
